      My latest core-XY is designed with all its motors outside the insulated chamber, away from the heat.

      With only x2 small openings on X/Y for the belt to come out and back in again,
      and the three lead screws coming up through the base of the chamber, chamber at chamber temp and motors at as near as dammit ambient.

        Good idea. I'm thinking of doing exactly the same with a printer I'm planning. But I'm also toying with the idea of building a conveyor type, "infinite Y" build platform. I don't think anyone has done that inside a heated chamber - could be my next challenge........

          I know not everyone uses Facbook, but I just saw a guy post on there who had built a belt Y axis printer from a re-purposed running machine.

          For one in a heated chamber I think the main challenge would be to safely get the print to transition from the chamber to the atmosphere and still keep the heat in the chamber.

            the voron ldo motors are rated to 180C. (130 chamber)

              LDO - that was the make I was trying to think of. Are you sure about the spec? I could be wrong but I thought the winding temp was 130 deg C meaning a chamber temp of 80 deg C.

                check the link. there are 4 high temperature motors with a winding temp of 180C

                    OK cool - I stand corrected.

                      That's the insulation class temperature. Without knowing the magnetic materials inside the motor it's hard to tell what's the curie point where the motors completely demagnetize. Most magnets also start losing power above 80C so it's best to keep their temperarures as low as possible.

                        What specific kind of failure does applying a heatsink or water jacket prevent?

                        Does a heatsink or water jacket cool the rotor where the magnets are located and separated from the stators by an air gap?

                          They prevent the loss of magnetism that happens in ferromagnets when temperature rises above their max working temperature point, until it reaches its curie temperature and completely demagnetizes.

                          Most motor magnets have the working temperature limit somewhere in the 80-160 range. Its never really stated properly and I wouldn't trust Chinese motors to use the proper materials.

                              @Veti I've looked at the dyze cooling blocks but they only cover a small surface area of the motor. I saw this https://www.researchgate.net/figure/a-Stepper-motor-cooling-shroud-installed-on-a-NEMA-17-stepper-motor-b-Computational_fig7_311666362 and i thought instead of running air through that heat shroud, run water and cool it further with a peltier. I think it looks promising as a better method of keeping the motors evenly cool.

                                  Cincinnati uses them in their SAAM HT and they seem to work fine.

                                    @Veti I ended getting 0.9 degree moons stepper motors and i'm hoping they can withstand the heat. A member on prusa forum did multiple test with moons motors and LDO motors and the moons out performed the LDO motors.

                                      I think his advise is dangerous and irresponsible but maybe that's just me .......

                                          yes i have read that article. heated chamber was not one criteria there though 🙂

                                            Does the rotor generate its own heat or does it get all its heat from the stators?
                                            Does applying a heatsink or water jacket to the motor's stators cool the rotor which is separated from the stators by an air gap?
